Abstract: the objective of this study was to evaluate the internal quality of eggs of japanese quails fed diets supplemented with chelated selenium and zinc. the experiment was carried out for 120 days, and 144 birds were divided in random blocks into four treatments (control; 0.3 ppm se; 60 ppm zn and 0.3 ppm se + 60 ppm zn). ten, 14, 18, and 22 weeks after the beginning of lay, eggs were collected and stored under two different temperatures (environmental temperature or refrigeration) and for 10, 20, and 30 days. eggs were analyzed for: haugh units (hu), albumen height (ah), yolk index (yi), and albumen index (ai). parameters were only statistically influenced by the interaction between dietary treatment and storage time. it was concluded that the addition of organic se and zn influenced internal egg quality when eggs were stored up to 20 days, independently of storage temperature, suggesting that the combined supplementation of organic se and zn improve internal egg quality and extend egg shelf life.

Abstract: The aim of this paper is to present a literature review on the current model of cadaster of rural properties in Brazil and its development. To analyze such an understanding is made from the appearance of land grants in the period of colonization of Brazil showing the importance of a system of land cadaster in structuring real estate in the country throughout history. The design cadaster is given in different ways and are identified according to some definitions of institutions and countries or continents. Currently the National Registry of Rural Properties is governed in accordance with Law 10,267 of 2001 and the responsibility of the National Institute of Colonization and Agrarian Reform (INCRA).O objetivo desse artigo é apresentar uma revis o de literatura sobre o atual modelo de cadastro de imóveis rurais no Brasil e o seu desenvolvimento. Para tal entendimento é feita análise desde o surgimento das sesmarias no período de coloniza o do Brasil mostrando a importancia de um sistema de cadastro imobiliário na estrutura o fundiária do país ao longo da história. A concep o de cadastro é dada de diferentes maneiras e s o apontadas algumas defini es de acordo com institui es e países ou continentes. Atualmente o Cadastro Nacional de Imóveis Rurais é regido de acordo com a Lei 10.267 de 2001 e de responsabilidade do Instituto Nacional de Coloniza o e Reforma Agrária (INCRA).

Abstract: O Brasil é o sexto maior produtor de leite do mundo. Atualmente, grande parte desta produ o provémde sistemas de produ o que utilizam as pastagens como principal fonte de alimento para os animais. Porém estaspastagens na maioria dos casos s o utilizadas de forma extensiva, ou seja, grandes áreas, com baixa qualidade eprodutividade. Dentre os diversos sistemas de produ o de leite existentes dois deles merecem destaque, o sistemaintensivo a pasto e o silvipastoril. O primeiro por conseguir maximizar a produ o de leite em áreas relativamentepequenas e o segundo devido às crescentes press es ambientais, sendo oportunidade de se produzir em ambientemais sustentável e com maior conforto animal. Esta revis o foi realizada com objetivo de caracterizar e compararestes dois sistemas de produ o de leite.Brazil is the sixth largest milk producer in the world. Currently, much of this production comes fromproduction systems that utilize pasture as the main source of food for animals. However, these pastures in most casesare used extensively, in other words, large areas with low quality and productivity. Among the various systems ofmilk production exist two of them thatdeserve special mention, the intensive grazing system and silvopastoral. Thefirst by getting maximize milk production in relatively small areas and the second due to growing environmentalpressures, and the opportunity to produce more sustainable environment and greater animal comfort. The objective ofthis review was to characterize and compare these two systems of milk production.

Abstract: OBJETIVO: Analisar, prospectivamente, os resultados da determina o do antígeno carcinoembriário (CEA) na bile vesicular, relacionando-os com os aspectos morfológicos e clínicos da neoplasia e recidiva hepática. MéTODOS: Os níveis do CEA foram estudados na bile vesicular e no sangue periférico de 44 doentes com carcinoma colorretal e 10 com colelitíase n o complicada, a partir de amostras do CEA colhidas imediatamente antes da extirpa o da neoplasia colo-retal e da colecistectomia (considerou-se valor normal até 5 ng/ml). RESULTADOS: Os 44 carcinomas colorretais extirpados com inten o curativa tiveram nível médio do CEA sérico de 8,5 ng/ml e CEA biliar, 74,5 ng/ml. Nas colelitíases n o complicadas submetidas a colecistectomia, o nível médio do CEA sérico foi de 1,9 ng/ml e CEA biliar, 1,2 ng/ml. Quatro doentes submetidos à extirpa o do carcinoma colo-retal, sem evidências de metástases hepáticas e com valor médio de CEA biliar de 213,2 ng/ml apresentaram metástases hepáticas entre três a 17 meses após a extirpa o. CONCLUS O: o nível elevado de CEA biliar dos operados por carcinoma colo-retal pode indicar presen a de metástases hepáticas e esses enfermos devem ser acompanhados com especial aten o para diagnosticar essas les es.
Inter-Network Resource Sharing in IEEE 802.22 Networks  [PDF]
Carla Passiatore, Pietro Camarda
Communications and Network (CN) , 2012, DOI: 10.4236/cn.2012.42015
Abstract: IEEE 802.22 is the first worldwide standard for Cognitive Networks (CNs) that exploits unused spectrum of the television broadcast service. An IEEE 802.22 network is also called Wireless Regional Area Network (WRAN). An open issue in cognitive 802.22 networks is represented by the resource distribution among WRANs. In this paper a protocol for radio resource management for CNs in a multichannel environment is presented and analysed. In particular, the contribution of this work is a resource sharing method to schedule the WRAN access to the available channels in a community made by two o more coexisting WRANs. The method adapts to the continuous changes of the spectrum availability due to necessity of vacating a channel in case of the incumbent primary users. Moreover, the introduced allocation scheme allows to divide the available band in a proportional way to the cognitive user spectrum demands, taking into account the issue of spatial diversity, i.e. the case where the channel coverage area is not uniform. The effectiveness of the proposed multichannel scheme is proved through simulations. The results compared favorably with other methods already known in literature and show that the proposed algorithm optimize the spectral efficiency, keeping high fairness as demonstrated computing the Jain’s index.
Energy and Sustainability in Museums. The Plant Refurbishment of the Medieval Building of Palagio di Parte Guelfa in Florence  [PDF]

Open Journal of Energy Efficiency (OJEE) , 2012, DOI: 10.4236/ojee.2012.13004
Abstract: This paper presents a performance-based design of a HVAC plant and controller system of the “Palagio di Parte Guelfa” Palace, a medieval building converted into a museum in the city of Firenze. Transient simulations to evaluate the internal microclimate conditions during the year for the building and the different system plant were carried out. A comparison between the indoor microclimatic parameters obtained and the values suggested by the standards on protection and conservation of historical works of art, suggested a non-invasive and reversible plant system solution. The MuseumofHistorical Footballbuilding portion is the case study. The proposed plant, a constant air flow system coupled with radiant panels dry mounted above the existing flooring, was simulated throughout the year under transient conditions to evaluate its energy performance. This solution ensures indoor temperature and humidity values suitable for the conservation of works of art and visitor comfort. It is an example of a possible course of action for a plant refurbishment in a historic building converted into a museum, located in climatic regions characterized by high thermal and solar loads. The present paper concerns the study of an integrated and reversible architectural-plant solution proposed: reversibility of the proposed system is understood as the possibility for the present conditions being easily restored.

Challenges of Effective Collaboration in a Virtual Learning Environment among Undergraduate Students  [PDF]
Russell Butson, Carla Thomson
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.516162
Abstract: Web-based technology has influenced the way we perceive and use computer devices. One effect of the increasing variety of online web services has been a move away from “personal” computing toward networked or “social” computing. In this paper we discussed a research project which explored the potential in using a purpose-built social-networked environment to support learning in undergraduate education. In particular, we were interested in which tools would be adopted and the collaborative manner which would be used. A prototype web-based networked environment was built that allowed each student a personal space with their profile, access to resources and a group-project work space. The network incorporated a people-centric paradigm that integrated networking across a range of collaborative tools to support course activities. The system embraced an “open” philosophy where all students and staff were linked to all members and work- group areas. Each work-group area consisted of a number of web-based tools that included a group wiki, group blog, file repository, weblink tool, discussion area, and calendar. The site allowed for both synchronized and asynchronized communication via messaging and chat facilities. The results showed that students did not work collaboratively and struggled to use the web-based tools to advance their learning. Further investigation revealed that students preferred individual offline approaches to the more demanding processes required in a collaborative online environment.
